Common Causes of Frozen AC Units
During the hot summer months, air conditioning may become essential for providing comfort and relief from the heat. However, one of the most common issues that people experience with their air conditioner is the freezing of their units. Unfortunately, this can be caused by several factors, all of which can be easily fixed with the help of a local and reliable appliance repair service.
Clogged Air Filter
When air filters become clogged, air flow is restricted and over time, this lack of air flow can cause the evaporator coil to freeze up. To prevent this from happening, it is important to change the filter regularly, as it is the easiest way to maintain good air flow. Depending on factors such as the environment of the home, outdoor environment and usage of the unit, filters can become clogged over time and need to be changed to provide the best performance as frequent as once a month. It is important to check air filters monthly and replace them when necessary for a frozen AC unit. It is also important to clean the filter at least once a month and make sure the entire coil is free from dirt and dust.
Low Refrigerant
In order for an AC unit to operate properly and prevent freezing, the refrigerant must be kept at a regulated level. If the refrigerant level is too low, the evaporator coil can freeze and disrupt the air conditioning system. This is because refrigerant circulates through the evaporator coil on the inside unit and absorbs heat from the air. If there is an issue with the refrigerant level, such as an undercharge, the evaporator coil can become too cold and thus freeze. Therefore, it is necessary to have the refrigerant levels checked regularly in order to make sure they are at an optimal level and that the system is working well.
Blocked Drain Line
When the drain line that is responsible for draining the pan that collects water from the air conditioner gets blocked, then the water can accumulate and freeze. This is because the water is frozen and prevents the condensation from going outside, which not only causes the system to stop functioning but can also cause other damages to the unit. In order to unblock the drain line, it is recommended to use a wire or a piece of pipe cleaner, but if the cause of the blockage is not found, it is best to contact a reliable appliance repair service for help.
Faulty Fan
The fan is responsible for pushing air over the evaporator coil and for providing the necessary air flow for cooling, so a faulty fan can cause the evaporator coil to freeze. This can happen due to a broken motor, a loose connection or a blown fuse, therefore, it is important to make sure the fan is correctly operating and if the issue persists, then it is best to contact an appliance repair specialist, who can inspect and repair the fan.
By understanding the common Causes of Frozen AC Units, it is possible to troubleshoot the issue before calling a professional.

Causes of Frozen AC Units
A frozen AC unit is a common issue with air conditioning systems, often caused by low refrigerant levels, blocked drainage, dirty filters, or lack of maintenance. While there is no surefire way to prevent a frozen AC unit, below are a few manufacturer recommendations, local appliance companies’, or HVAC technician’s recommendations for preventing a frozen AC unit.
Check Debris and Clean Filters
The first recommendation is to check for debris surrounding or inside the AC unit and to clean or replace filters if needed to allow for proper airflow. Additionally, taking a look at the central unit’s fins and checking for debris or leaves also helps to ensure proper airflow to the entire system.
Check for Obstructions
Next, checking for potential obstructions within the line set or AC unit, as low refrigerant levels can cause the system to freeze. If there are any obstructions, these will need to be addressed and cleaned up in order to prevent any freezing.
Check Drainage
It’s also important to check the drainage system and make sure that there are no blockages in the float switch or drain line that could prevent the proper drainage of water from the unit. If you notice any blockages, this should be cleared up as soon as possible.
Check the Thermostat
Finally, it’s key to keep the thermostat level and ensure that it is set in the proper location in order to ensure the optimal airflow throughout the system. This can also help reduce the risk of a frozen AC unit.
Overall, regularly cleaning filters, checking for obstructions, ensuring proper drainage, and inspecting the thermostat will help to minimize the chances of a frozen AC unit. If issues persist, contacting a local HVAC technician is advised in order to properly diagnose and solve the underlying issue.
The True Cost of Frozen AC Units: Professional Advice
Frozen AC units can cause costly damages and can be difficult and expensive to repair, but understanding the underlying causes of the issue is the best way to prevent long-term issues from arising. Learn the facts about what causes AC units to freeze up, explore average repair costs, and get the best advice for keeping the system running efficiently.
An AC unit freezing up can have a number of underlying causes. Common issues include a blockage of the condensate drain line, a low level of coolant, a malfunctioning fan, or a dirty air filter. To address the issue, a qualified HVAC technician might need to replace or clean parts such as the outdoor condenser unit, fan belt, blower assembly, evaporator coil, or even the condenser fan.
The minimum repair cost for frozen AC units is typically around $300, but more complex repairs can seen run up to $1,000 or more. In more expensive cities such as California, repair costs are typically 20% higher than the national average. In addition to repairs, materials such as coolant and filters may be needed and these typically cost an additional $50 – $100; however, if repairs are needed it’s likely that the HVAC technician will include the cost of these materials in the repair quote.
For the best advice on avoiding frozen AC units, contact a local reliable air conditioning and heating specialist. HVAC specialists are trained in AC maintenance, repair and installation and offer the best advice when it comes to preventing costly breakdowns.

Reliable Air Conditioning & Heating, an experienced and family-owned California business, offers top-notch same-day service for appliance and HVAC repair, installations and diagnostics in an effort to determine the problem and come up with a resolution.
The causes of frozen AC units range from dirty filters to worn-out components. The most common causes of freezing ACs are:
– Low levels of refrigerant: Low levels of refrigerant cause your AC to freeze up because the air passing through the coil doesn’t get cold enough to allow proper condensation.
– Clogged air filter: Clogged air filters restrict the airflow, which not only makes the unit work harder to cool the air, but also reduces its efficiency.
– Improperly sized unit: An air conditioning unit that’s too small for the space it’s cooling can’t keep up with the demand, which leads to freezing.

FAQ About Common Causes of Frozen AC Units
What Causes an AC Unit to Freeze?
A frozen AC unit is typically caused by low refrigerant levels, a blocked filter, an oversized system, or excessive air flow issues. Low refrigerant or coolant levels can lead to an AC unit freezing due to a lack of thermal transfer across the evaporator coil. Blockages in the air filter can lead to the same issue, as it prevents the necessary air flow to keep the heat exchange balanced. Additionally, an AC unit that is too large for the space it is cooling can also lead to freezing issues by running too long, dehumidifying the air, and dropping temperatures too low.
What are Some of the Early Signs of a Frozen AC Unit?
The most common signs that an AC unit has begun to freeze over include reduced air flow, increased cooling time, and frost accumulation on the evaporator coil. If the unit continues to operate when it has started to freeze over, it can also produce odd noises due to the ice interfering with components as it expands.
How Can I Prevent My AC Unit From Freezing?
The best way to prevent an AC unit from freezing is to regularly maintain the system, and perform yearly service. During maintenance, the service technician should inspect the system for the common causes of AC freezing, such as improper refrigerant levels, blocked filters, condensation drainage problems, and other signs of strain.
If you find that your AC unit has started to freeze up, it is best to call a local, reliable appliance repair service for help. To get your AC unit fixed quickly and safely, call Local Reliable Appliance Repair at (866) 311-8590.
